As I'm sure has been said before, the MJ teaching model aims to attract and retain the maximum number of people who just want to dance socially. This certainly works - I've seen people who have been going to intermediate classes for years, have been taught hundreds of intermediate moves and goodness knows what (if anything) on technique, musicality etc, but are quite happy to keep on dancing the same old beginner moves over and over again. It certainly works for these leaders and presumably the followers who dance with them.

Of course, a percentage will want to move on and actually learn how to dance to a piece of music, whether that be MJ or something more demanding. Around that time the emphasis shifts from moves to technique.

And yes, bring back some of the old and rarely seen MJ moves, I have a good store of them written up somewhere and occasionally introduced.

Not only that, just make up your own moves anyway, from other dance forms, old dance films and documentaries, whatever.
